Important Announcement for Endicia Customers:
Endicia is Disabling Support for TLS 1.0

June 1, 2018

Notice from Endicia:

"As part of our ongoing efforts to enhance security and protect your sensitive data,
Endicia will no longer support the use of Internet security protocol, Transport Level
Security (TLS) 1.0. This change is part of an industry-wide regulation from the PCI
Security Standards Council.

"Starting on Saturday, June 30, 2018, Endicia will require the use of TLS 1.1 or higher
to establish secure connections. Please ensure your application is able to connect
with our APIs using TLS 1.1 or higher. Attempting to connect to our APIs using TLS
1.0 will result in a communication error.

"We do not expect this change to cause connectivity issues for the vast majority of users;
however, users on older operating systems or browsers may experience limited to no
connectivity to Endicia. Here is a list of operating systems and browsers that will no
longer be supported once TLS 1.0 is disabled:

Microsoft Windows Vista

Microsoft Windows XP

Microsoft Windows 2003

MacOS 10.8 and below

Internet Explorer versions 10 and below

Mozilla Firefox versions 26 and below

Google Chrome versions 29 and below

Apple Safari versions 6 and below

"We will provide advanced notice when TLS 1.0 is disabled in the Endicia sandbox,
to assist you with any necessary testing efforts. Please reach out to us immediately at
Business-Partner@Endicia.com
if you have any other questions."
